Illuminated Crystal

Crystal that can be illuminated by RGB LED. Lipo battery and charge controller are integrated in the base. Of course the Led can also be supplied directly with the Usb voltage of 5V. Then a resistance of 68 Ohm instead of 22 Ohm would have to be used.

The figure is printed without infill.
My slicer settings for the figure (Cura):
Layer hight: 0,1
Wall thickness: 1.2 (3 x 0.4 wall lines)
Top/Bottom Thickness: 0,8
Filling: 0%.
Combing mode: off

The white filament should be translucent. Suitable are e.g.: Geeetec or janbex.
Printing without filling is only possible without a hole at the bottom. Therefore the hole at the bottom has to be drilled after the printing.
